PR Transferase, Anthranilate

Phosphoribosylanthranilate Pyrophosphorylase

Phosphoribosyltransferase, Anthranilate

Pyrophosphorylase, Phosphoribosylanthranilate

An enzyme that catalyzes the formation of N-5'-phosphoribosylanthranilic acid from anthranilate and phosphoribosylpyrophosphate, the first step in tryptophan synthesis in E. coli. It exists in a complex with ANTHRANILATE SYNTHASE in bacteria. EC 2.4.2.18.
